Title: Decomposition of ilmenite
IPC: C01G49/10
Filed: 1966-12-07
Abstract: Ilmenite is contacted with elementary carbon and bromine in an inert carrier gas at an elevated temperature not above 1000 DEG  C., to form FeBr3 which is recovered separately from the unreacted TiO2. The carbon source may be coke and the ilmenite-carbon mixture briquetted before use.  The carrier gas may be nitrogen or a mixture of nitrogen and carbon dioxide.

Title: Rolling stand for rolling elongate stock
IPC: B21B13/10
Filed: 1973-11-30
Abstract: 1440633 Rolling mills FRIEDRICH KOCKS 30 Nov 1973 [2 Dec 1872] 55619/73 Heading B3M A roll stand for rolling wire or tube has at least three rolls 2 which are simultaneously radially adjustable by means of a common adjusting spindle 12. Each roll is carried on a driven shaft 4, Fig. 1, which is supported by bearings 6, 6a and 8 in respective bushes 7 and 7a. The bushes, when rotatably adjusted within the stand housing 1 by means of the spindle 12, cause an eccentric adjustment of the shafts and rolls in a radial direction. The bushes 7 are coupled together by bevel gears 11  to ensure simultaneous movement of the rolls. Each roll may have an outer annulus 2a clamped between two discs 2. The discs are mounted on portions 4a and 4b of the shaft 4 which are clamped together by a central draw bolt 5. The roll may be adjusted axially by rotating a threaded collar 9 within the bush 7a. The collar may also be used for allowing removal of the annulus 2a by moving the discs 2b apart, after withdrawing the bolt 5. In an alternative form, Fig. 3, the bushes 7 are similarly adjusted, but the rolls are driven by a common spindle 22. Bevel gearing 23 couples the shafts together for common rotation. Since radial adjustment of the rolls then interferes with correct meshing of the gearing 23, the bushes are arranged to move. axially during their rotational adjustment. This is effected by externally threaded rings 24 which co-operate with fixed threaded stops (Fig. 5, not shown). Alternatively, the gearing 23 may be made independent of radial adjustment of the rolls (Fig. 7, not shown). In this case, the shaft parts 4b co-operate by, e.g. a toothed connection with the interior of bushes carrying the gearing. The roll stand can process hot or cold stock, and the rolls can be mounted on tapered portions of the shafts 4, in which case pressurized oil may be employed for their removal from the shafts.

[Also in Division H4] A plasma aerial comprises radiating conductive elements and a device for varying the radiation frequency characteristic of said aerial in a plasma. The device has adjustable means for modifying the thickness or the density of the ionic sheath between the elements and the plasma. As described, a gas discharge tube has a spherical glass central part 31, Fig. 1, with two cylindrical extensions 32, 33 at the respective ends of which are a thermionic cathode 10 and an anode 11. Absorbent screens 39 are mounted about the exteriors of the cylindrical extensions 32, 33. Extending transversely to the tube is a coaxial cable 36 terminating in two separate but closely spaced metallic hemispheres 34, 35. The tube contains mercury vapour at 2 x 10<SP>-3</SP> torr for sustaining an arc and producing a plasma when suitable potentials are applied to the anode and the cathode. The cable 36 is connected to a balun 38, and the hemispheres 34, 35 are thereby excited with R.F. energy from a generator 37, and are biased with respect to the cathode 10 by means of a D.C. source V. The density of the plasma may be controlled by varying the discharge current, and the ionic sheath between the plasma and the hemispheres 34, 35 may be further controlled by varying the biasing voltage V. In this way, the aerial may be matched for maximum radiation efficiency over a band of frequencies. It is stated that the aerial is particularly suitable for aircraft or satellites, and that the plasma may be of natural origin, e.g. re-entry plasma.
